Question # 19

What are the four different risk response techniques?

Question # 20

Describe the security principle of simplicity.

Because attacks can come from a variety of sources and in many ways, information security is by its very nature complex.

The more complex something becomes, the more difficult it is to understand.

In addition, complex systems allow many opportunities for something to go wrong.

Complex security systems can be hard to understand, troubleshoot, and feel secure about.

As much as possible, a secure system should be simple for those on the inside to understand and use.

Complex security schemes are often compromised to make them easier for trusted users to work with, yet this can also make it easier for the attackers.

In short, keeping a system simple from the inside but complex on the outside can sometimes be difficult but reaps a significant benefit.

The foundational Python concepts covered in this module serve as building blocks, empowering participants with the skills necessary to navigate and leverage Python effectively in various cybersecurity scenarios. This comprehensive exploration ensures that participants not only comprehend the theoretical underpinnings of Python but also acquire practical proficiency, positioning them as adept practitioners in the dynamic field of cybersecurity.

Learning Objectives

• Explain how the Python programming language is used in security.
• Describe how various data types are handled in Python.
• Incorporate variables into Python code.
• Write conditional statements in Python.
• Write iterative statements in Python.

TEST YOUR KNOWLEDGE: INTRODUCTION TO PYTHON PROGRAMMING IN CYBERSECURITY

1. what tasks would a security analyst most likely automate with python select three answers..

• Managing an access control list (CORRECT)
• Analyzing network traffic (CORRECT)
• Sorting through a log file (CORRECT)
• Addressing an unusual cybersecurity concern

A security analyst would most likely automate the following tasks with Python: sorting through a log file, managing an access control list, and analyzing network traffic. Python is most commonly used in cybersecurity to automate common and repetitive tasks.

2. What are some benefits of using Python in security? Select all that apply.

• Python reduces manual effort. (CORRECT)
• Python can combine separate tasks into one workstream. (CORRECT)
• Python is the only language that creates a specific set of instructions to execute tasks.
• Python helps automate short, simple tasks. (CORRECT)

Python reduces the manual effort needed to perform common and repetitive tasks. It helps automate short, simple tasks and can combine separate tasks into one workstream.

3. Which of the following code blocks contains a valid Python comment?

This prints a “try again” message.

• print(“Try again”)
• : This prints a “Try again” message
• comment: This prints a “Try again” message
•  # This prints a “Try again” message
• print(“Try again”) (CORRECT)

The following code block contains a valid Python comment:

• # This prints a “Try again” message

A comment is a note programmers make about the intention behind their code. Comments begin with the hash symbol (#).

4. Which line of code outputs the string “invalid username” to the screen?

• print(invalid username)
• # print(“invalid username”)
• print(“invalid username”) (CORRECT)
• print(#invalid username#)

The code print(“invalid username”) outputs the string “invalid username” to the screen. The print() function outputs the object specified inside the parentheses to the screen. To output a string, it must be placed in quotation marks.

5. Why might a security analyst choose Python to automate tasks? Select three answers.

• Python programmers can follow standard guidelines. (CORRECT)
• Python runs faster than other programming languages.
• Python programmers can find a lot of support online. (CORRECT)
• Python resembles human language and is easy to read. (CORRECT)

A security analyst might choose Python to automate tasks because they can find a lot of support online and follow standard guidelines. An analyst might also choose Python to automate tasks because it resembles human language and is easy to read.

6. Which of the following options is a Python comment?

• % Display authorized users
• print(“username”)
• # Print authorized usernames (CORRECT)
• “username authorized”

# Print authorized usernames is a Python comment. Comments are notes that programmers make about the intention behind their code, and they begin with the # symbol.

TEST YOUR KNOWLEDGE: CORE PYTHON COMPONENTS

1. which of the following data items are float data select all that apply..

• 15.0 (CORRECT)
• -2.11 (CORRECT)

15.0 and -2.11 are examples of float data. Float data is data consisting of a number with a decimal point.

2. What code displays the data type of the variable username?

The data type of the variable username is displayed by the following code:

The type() function returns the data type of its input. In this case, that input is the username variable, which contains a list. This data type is assigned to the data_type variable and is displayed through the print() function.

3. In the following code, what is the data type of login_success?

• List (CORRECT)

List is the data type of login_success. List data is a data structure that consists of a collection of data in sequential form. Lists are placed in brackets.

4. What is the output of the following code?

• 4 (CORRECT)

The output of the code is 4. This code initially assigns the value of failed_attempts to 3, but it then reassigns the value of this variable to 4 before printing it. The print() function is placed after this and displays this reassigned value of  4.

5. Which data type can only have a value of True or False?

• Boolean (CORRECT)

The Boolean data type can only have a value of True or False. Boolean data is data that can only be one of two values: either True or False.

6. Which of the following lines of code assigns the variable username a value of “jrafael”?

• “jrafael” = username
• print(“jrafael”, username)
• print(username, “jrafael”)
• username = “jrafael” (CORRECT)

The code username = “jrafael”  assigns the variable username a value of “jrafael”. The syntax for assigning a variable requires a name for the variable, then an equals sign (=), and finally the value for the variable.

TEST YOUR KNOWLEDGE: CONDITIONAL AND ITERATIVE STATEMENTS

1. what will the following code display.

• Both “You’re logged in.” and “Login failed, try again.”
• “Login failed, try again.”
• “You’re logged in.” (CORRECT)

The code will display “You’re logged in.” The condition in the if statement requires the ip_address variable to contain a value of “192.168.183.51”. Because this condition evaluates to True, Python will perform the action specified in the body of the if statement. In this case, it displays the message “You’re logged in.” The action specified in the body of the else statement will only execute when the condition in the if statement evaluates to False, so it will not print “Login failed, try again.”

2. Which conditional statement prints the message “account locked” when the value of failed_logins is 3 or higher?

The following conditional statement prints the message “account locked” when the value of failed_logins is 3 or higher:

This condition checks if failed_logins is assigned a value that is greater than or equal to 3. The operator >= represents greater than or equal to. When this condition is met, the body prints the “account locked” message. 

3. Which code prints all numbers from 3 to 7?

The following code prints all numbers from 3 to 7:

The range() function generates a sequence of numbers. With range(3, 8), the sequence will start at 3 and end at 7. This is because the number in the first position, 3, is included in the sequence, but the number in the second position, 8, is excluded. 

4. How many times does the following code print the “security alert” message?

• 10 (CORRECT)

This code will print “security alert” ten times. This is because the count variable is assigned an initial value of 0. It then increments by 1 with each iteration of the loop until the condition instructs it to stop at 10.

5. Which operator can be used in a condition to evaluate whether the value contained in a login_attempts variable matches a value of 5?

• == (CORRECT)

The == operator evaluates whether two objects match and can be used in a condition to evaluate whether the value contained in a login_attempts variable matches a value of 5. This condition can be placed in an if statement header as if login_attempts == 5.
